Cap Head Seal Screws

In stock

Seal screws are a type of fastener designed with an o-ring to provide secure bi-directional protection against contaminates such as gases and fluids in various applications, minimising the risk of damage to sensitive equipment. They prevent the entry of water, dust, or other contaminants, ensuring a secure, reliable connection.

Seal screws are used in threaded and non-threaded holes in applications such as cabinets or used in the automotive and electric industries.

This range of sealing screws has a cap head with a torx socket drive incorporates an O-ring which is compressed, squeezed between the head and the socket drive, and the mating surface to complete the seal. They are manufactured from stainless steel, which provides good corrosion resistance and is slightly magnetic.

Please note: Our seal screws are designed for use in applications where sealing properties are required. It could be confused with standard fasteners, these do not require sealing properties and with an O-ring you will not get a sealing property like you get with seal screws and may damage the ring.

  • Material: Stainless Steel
  • AISI 303, 1.4305 or AISI 316, 1.440
